Calculation Priority SequenceYour ClassPad automatically performs calculations in the following sequence.

1Commands with parentheses (sin(, diff(, etc.)2Factorials (x!), degree specifications (o, r ), percents (%)3Powers

4π, memory, variable multiplication operations that omit the multiplication sign (2π, 5A, etc.), command with parentheses multiplication operations that omit the multiplication sign (2'3, etc.), ×, ÷

5+, –, (–)6Relational operators (=, , <, >, s, t)7and8or, xor9with ( )

Tip

•Expressions in parentheses are given priority.

•In cases where a series of calculations in the same expression includes more than one of the operators 4 through 9 that are the same priority sequence level, the same level operations are performed from left to right. A series of power calculations 3 (example: 5^2^3) is performed from right to left (5^(2^3)).

Example: 2 + 3 × ( log ( sin( 2π2 )) + 6.8 ) = 22.07101691 (In Algebra mode, Decimal mode, Radian mode)

Calculation Modes

All of the following calculation examples are shown using the Algebra mode only.

Standard Mode and Decimal Mode

The Standard mode displays calculation results in mathematical expression format whenever possible, while the Decimal mode converts calculation results to a decimal form.

		Expression	Decimal Mode Result	Standard Mode Result
50		÷ 4 = 12.5	12.5	25
				2
		+ 2 = 3.414213562...	3.414213562	2 +
	2							2
π = 3.1415926535...			3.141592654					π
					5 · (		− 1)
sin (2.1π) ⋅ 5 = 1.5450849718...			1.545084972			5
				4

•The Decimal mode results in the above table show what would appear on the display when “Normal 1” is selected for the [Number Format] setting on the Basic Format dialog box.

uUsing the u Button to Toggle between the Standard Mode and Decimal Mode

You can tap u to toggle a displayed value between Standard mode and Decimal mode format.

Note that tapping u toggles the format of a displayed value. It does not change the current Standard mode and Decimal mode setting.
